下面的示例演示如何使用WindowsIdentity类的成员。The following example shows the use of members of WindowsIdentity class. 有关演示如何通过调用非托管的 Win32 LogonUser函数获取 Windows 帐户令牌并使用该令牌来模拟其他用户的示例, WindowsImpersonationContext请参阅类。For an example showing how to obtain a Windows account token through a call to the unmanaged Win32 LogonUser function, and use that token to impersonate another user, see the WindowsImpersonationContext class.

重要

此类型实现 IDisposable 接口。This type implements the IDisposable interface. 在使用完类型后,您应直接或间接释放类型。When you have finished using the type, you should dispose of it either directly or indirectly. 若要直接释放类型,请在 try/catch 块中调用其 Dispose 方法。To dispose of the type directly, call its Dispose method in a try/catch block. 若要间接释放类型,请使用 using(在 C# 中)或 Using(在 Visual Basic 中)等语言构造。To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). 有关详细信息,请参阅 IDisposable 接口主题中的“使用实现 IDisposable 的对象”一节。For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.
